Challenges And Security Strategies Of China’S Critical Metals Supply For Carbon Neutrality Pledge, Weiqiang Chen, Peng Wang, Weiqiong Zhong
Challenges And Security Strategies Of China’S Critical Metals Supply For Carbon Neutrality Pledge, Weiqiang Chen, Peng Wang, Weiqiong Zhong
Bulletin of Chinese Academy of Sciences (Chinese Version)
The grand transition to low-carbon energy system is essential to bend the growing carbon emission and further achieve the dual carbon goals. Critical metals such as rare earth elements, lithium, cobalt, nickel, and platinum are widely considered as the material base to support low-carbon technologies. However, given the supply of those metals are scarce and risky, the emerging conflicts between their supply and demand have spurred global attention and competition among countries. This study aims to explore the linkage between critical metals and low-carbon energy systems with a particular focus on the bottlenecks of China's supply chains of those critical …

Typical Pathway To Carbon Neutrality For Urban Smart Energy Systems—Case Study Of Macao Special Administrative Region, Yonghua Song, Hongcai Zhang, Ge Chen
Bulletin of Chinese Academy of Sciences (Chinese Version)
China's ambitious goal "strive to peak carbon emissions before 2030 and achieve carbon neutrality before 2060" not only shows China's responsible attitude towards climate change, but also aligns with the upgrade requirement of China's economy and industries. Since cities occupy a dominant position in China's population, energy consumption, and carbon emissions, they are the main battlefield for achieving national carbon neutrality. This study first analyzes the challenges and requirements that cities' energy systems facing in order to realize carbon neutrality. Then, it takes Macao as an example to analyze the characteristics of cities' energy consumption and carbon emissions. Finally, it …
Global Technology Of Ocean Carbon Sequestration Based On Patent Analysis, Tianyue Peng, Dehao Tang, Liqiang Liu, Bing Han, Benduo Zhu
Global Technology Of Ocean Carbon Sequestration Based On Patent Analysis, Tianyue Peng, Dehao Tang, Liqiang Liu, Bing Han, Benduo Zhu
Bulletin of Chinese Academy of Sciences (Chinese Version)
The ocean is the largest and most active carbon reservoir in the world. Through ocean-atmosphere exchange and the photosynthesis of marine plants, the uptake of carbon dioxide (CO2) by the ocean is much greater than that by soil and vegetation on terrestrial areas. This is essential to mitigate and ameliorate today's global warming which is caused by rising atmospheric CO2 concentration. Therefore, to achieve the goal of "carbon neutrality" around the country, it is an effective approach to sequester CO2 in the ocean. This paper summarizes the technical application scope and methods of ocean carbon sequestration. By analyzing correlative patents …

Systematic Study On Carbon Emission Reduction Of Municipal Solid Waste Treatment, Jisheng Long, Hailiang Du, Xin Zou, Jingying Huang
Bulletin of Chinese Academy of Sciences (Chinese Version)
Under the context of China's carbon peak and carbon neutrality, the treatment of municipal solid waste (MSW) is facing new challenge to reduce carbon emission. This study suggests that significant carbon emission reduction and dual cycle of mass and energy can be realized, under the context of MSW classification, by the collaborative treatment of multi-source solid waste in Eco-Industrial Park. Results showed that in 2020, the incineration and landfilling of MSW in China reduced 5.18 million tons of CO2 emission, at the same year, 15 million tons of CO2 emission could have been reduced if the wet waste was treated …
Review Of Eu’S Carbon Neutral Policy System And Its Enlightenment, Liping Dong, Jingjing Zeng, Jiansheng Qu, Huijuan Pei, Qin Liao, Yanfei Liu, Lina Liu, Bingxue Qin

Bulletin of Chinese Academy of Sciences (Chinese Version)
Carbon neutrality is a redefinition of human development mode, and a "self-reform" of the production paradigm. It not only affects the economic development of various countries, but also rebuilds the global geopolitical pattern. Since 2060 carbon neutrality target was proposed in September 2020, China has been working hard on exploring how to establish a system of the carbon neutral policy. By considering the system of carbon neutral policy in European Union that is relatively mature, this study comprehensively reviews and analyzes the EU's system of carbon neutral policy from policy framework, key industry measures, R&D deployment support, and fiscal and …
Research On China’S Energy Development Strategy Under Carbon Neutrality, Jian Su, Yingbo Liang, Lin Ding, Guosheng Zhang, He Liu

Bulletin of Chinese Academy of Sciences (Chinese Version)
China has pledged to reach peak carbon dioxide emission by 2030, and carbon neutrality by 2060 at the Seventy-Fifth Session of the United Nations General Assembly in 2020. As the largest energy consumer and emitter of greenhouse gases, carbon peak and carbon neutrality targets have posed a high requirement for China's sustainable development of energy and economy. In recent years, even though the growth rate of China's energy consumption has decreased, and carbon dioxide emissions gradually enter the plateau, fossil fuels still supply more than 80% of the energy consumption in China. Besides learning from the adjustment of energy consumption …
Toward Carbon Neutrality: Circular Economy Approach And Policy Implications, Wendong Wei, Zhujun Chen, Yong Geng, Wenqiu Cai, Hanbin Liu
Toward Carbon Neutrality: Circular Economy Approach And Policy Implications, Wendong Wei, Zhujun Chen, Yong Geng, Wenqiu Cai, Hanbin Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
It is challenging to promote global climate change governance under the current complicated international contexts. As a country with the largest carbon emission, China has committed to achieve carbon peak by 2030 and carbon neutrality by 2060. However, carbon neutrality is a complex system engineering and relies on the implementation of circular economy. Based upon “3R” principles of reduce, reuse, and recycle, this study investigates the internal relations between circular economy and carbon neutrality and identifies the key position of circular economy in achieving carbon neutrality targets. Several policy implications are raised to help promote the development of circular economy …
Evaluating Economic And Social Benefits Of Accelerated Energy Transition, Hongyu Zhang, Xiaodan Huang, Da Zhang, Xiliang Zhang
Evaluating Economic And Social Benefits Of Accelerated Energy Transition, Hongyu Zhang, Xiaodan Huang, Da Zhang, Xiliang Zhang
Bulletin of Chinese Academy of Sciences (Chinese Version)
To achieve carbon neutrality, China's energy system needs a radical transition, and the development of new energy is of central importance. Based on the integrated assessment modeling framework, this study compares economic and social costs and benefits between a scenario reflecting the current energy transition momentum and a scenario of accelerated energy transition. We show that the accelerated energy transition dominated by new energy is essential to achieve carbon neutrality before 2060 and the air quality target required by Beautiful China. The large development of wind and solar power will further reduce their technology costs and the overall energy costs, …

Energy Revolution Under Vision Of Carbon Neutrality, Zhen Huang, Xiaomin Xie
Bulletin of Chinese Academy of Sciences (Chinese Version)
Climate change has emerged as one of the major challenges faced by mankind. It has become a non-traditional global security issue, which causes a serious threat to the survival of human being and sustainable development. China's commitment to peak carbon emissions by 2030 and achieve carbon neutrality by 2060 has important strategic significance for building a modern socialist country with harmonious coexistence between human and nature. Facing the challenge of China's carbon peak and carbon neutrality, this study proposes, through energy revolution, to promote electric decarbonization and zero carbonization power and zero carbonization fuel on the energy supply side, and …
